The attached pic was posted to a facebook group.

Date is around 1926 - based on the scaffolding on St Paul's cathedral.

It clearly shows the single curve used to get electric trams into Flinders St for the first section of that street to get electric services and also shows a couple of single truckers in Swanston St - one P&MTT or HTT and one MB&CTT.

The single truckers were taken out of Swanston St as quickly as possible - being replaced by the larger W class.
